Conduction, Convection & Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy in the form of electromagnetic waves, which can occur through empty space.

Front

Give an example of conduction.

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot pot of soup.

Front

Give an example of convection.

Back

An example of convection is warm air rising and cool air sinking in a room, creating a circulation of air.

Front

Give an example of radiation.

Back

An example of radiation is feeling the warmth of the sun on your skin.

What type of thermal energy transfer can occur in liquids and gases?

Back

Convection occurs in liquids and gases.

Front

What type of thermal energy transfer can travel through empty space?

Back

Radiation can travel through empty space.
